Solved Riding And Rider Code,EntityLink

Hello, I Need a Code EntityLink Packet That Works on Pocketmine 3.14.0 I tried using the code first, but an error

public function addLink(Entity $entity, int $type): void {
$this->eid = Entity::$entityCount++;
$this->removeLink($entity, $type);
$viewers = $this->getViewers();

switch($type) {
case self::LINK_RIDER:
$link = new EntityLink();
$link->fromEntityUniqueId = $this->getId();
$link->type = EntityLink::TYPE_RIDER;
$link->toEntityUniqueId = $entity->getId();
$link->immediate = true;
$link->causedByRider = true;

if($entity instanceof Player) {
$pk = new SetEntityLinkPacket();
$pk->link = $link;
$entity->dataPacket($pk);

$link_2 = new EntityLink();
$link_2->fromEntityUniqueId = $this->getId();
$link_2->type = EntityLink::TYPE_RIDER;
$link_2->toEntityUniqueId = 0;
$link_2->immediate = true;
$link_2->causedByRider = true;

$pk = new SetEntityLinkPacket();
$pk->link = $link_2;
$entity->dataPacket($pk);
unset($viewers[$entity->getLoaderId()]);
}
break;
case self::LINK_RIDING:
$link = new EntityLink();
$link->fromEntityUniqueId = $entity->getId();
$link->type = EntityLink::TYPE_RIDER;
$link->toEntityUniqueId = $this->getId();
$link->immediate = true;
$link->causedByRider = true;

if($entity instanceof Player) {
$pk = new SetEntityLinkPacket();
$pk->link = $link;
$entity->dataPacket($pk);

$link_2 = new EntityLink();
$link_2->fromEntityUniqueId = $entity->getId();
$link_2->type = EntityLink::TYPE_RIDER;
$link_2->toEntityUniqueId = 0;
$link_2->immediate = true;
$link_2->causedByRider = true;

$pk = new SetEntityLinkPacket();
$pk->link = $link_2;
$entity->dataPacket($pk);
unset($viewers[$entity->getLoaderId()]);
}
or is there an error in the code, correct me

 

EntityLinkPacket -> ActorLinkPacket
SetEntityLinkPacket -> SetActorLinkPacket
